DASS-015 A record of two days without parents, fucking my sister raw and busting inside her non-stop. Satsuki Gaei

My sister, Mei, is quiet and shy but has always been affectionate towards me. Unbeknownst to our parents, she has a strong curiosity about sex, and I have been sexually harassing her since long ago. Even now that I live alone. One day, my parents went back to their hometown to check on our grandfather's injury. However, Mei did not want to go with them, so my parents hesitated to leave their teenage daughter home alone and called me over. Alone with my sister, we crossed the line and had sex passionately.
